DIY Tech & Repairs

The new DIY and tech channel. Currently mainly tied into 18650 batteries and renewable energy from solar.

But its so much more! Tools, reviews, Locost build and car repairs. I also do stuff on request!

For reviews: Send me a PM and il send you address. All reviews are done fair and square and If i think the product is worth the time i also make the review!



Check out my articles on diytechandrepairs.nu (Pending rewamp so will come back in short)


Also dont forget my Patreon (www.patreon.com/diytech)
or if you like more direct-style you can always Paypal me at [email protected] or www.paypal.me/diytechandrepairs


Let us build up this channel to something big and independent. Its time to get this going! Let us all learn new stuff

    The problem with this is. The medium that's shorting out the battery needs to be able to withstand the buildup of heat in the battery. If you're using the stranded wire. You need to make sure that it continuously keeps a good connection. If you're using nickel strip you got to make sure the way you attached it and then they will strip itself can handle the heat. But the easiest way to short out a . It is too short out the positive contact with the case of the battery. The shorter length of whatever you're using would provide least resistance and let the battery get hotter

    Just an observation, not knowing the exact product number, but assuming 4 Ah per cell: I count 180 cells from your video. Considering it requires 4 cells in series to get 12.8 v, then paralleling the 45 series groups yields 180 Ah capacity theoretically. Not a detracting observation to your well presented info.

    Have you ever had overheating with this chip? My board looks exactly the same, but there's a notorious overheating issue that seems to be occurring with these boards recently which may be related to a cheap Chinese supplier. I have been trying to get my TTL<->RS232 connection to work with a firewall console cable -- almost the same as your setup -- except I'm using RJ45 pins 3,5,6 (rx,gnd,tx) and having a heck of a time getting it to work consistently.

I would like to switch automatically one battery power bank to another when the voltage drop, the switch’s I found don’t handle 100amp input. Any suggestions how to find?

    Where would i go in those git hub files to change the serial port command set? I have a Steca, but it uses many of the same codes, just for different functions. I thought I would see at least outlandish values, but I get 0 for every field. I even reversed the tx and rx just in case. The same pinout on a usb to serial works fine, so it's not the cable...I fear it's the operator. There are values in Wifi topic, but every other topic is blank. I tried MPI and PIP. No change.
